IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent N0. 92,@03, dated July '20,1869.

To all whom, it 1v1/ay concern,.-

Be it known that I, A. N. EDWARDS, of Greenville, Butler county, in theState of Alabama, have invented a new and useful Improvement in Plows;and I do hereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art to makeand use the same, reference being had to the accompanying drawings,forming part of this speciiication, in Which- Figure 1 represents a sideview, partly in section, of my improved plow. Fig. 2 is a back view ofthe same. Fig. 3 is a front view of the same.

Similar letters of reference indicate like parts.

This invention relates to a new fastening device for plowsand shovels ofall kinds, its object being to retain the share firmly and still toallow the ready removal and replacement of the same, so that shares andshovels of different kinds rnay be used on one standard.

The invention consists in the application of a T-shaped bolt forfastening the upper part of the share to the perforated standard, and,in combination with the same, of a brace for steadying broad shares.

A in the drawings represents a plow-standard, of suitable form and size,fastened to a plow-beam in the ordinary or suitable manner.

C is the plowshare or shovel, of suitable kind, to be fastened to thecurved or other face ofthe standard. The upper part of the shovel isnotched, as in Fig. 3, to t over a projecting edge, a, formed on theface of the standard. This projecting edge or ridge a is slotted and thestandard perforated to allow a T- shaped bolt, D, to be fitted throughit, the transverse head b of the bolt resting on the share, as shown. Awedge, c, nut, or other equivalent device is used to draw the head ofthe bolt firmly down upon the share, so as to clamp the share firmly.For small shares and shovels this clamping device will be sufficient."For larger shares a bolt, d, may be used to fasten their lower parts, asshown.

For farmingshovels, cottonscrapers, or other large plows, a brace, E,may be used, besides the aforesaid fastening devices, said brace beingwith one end fastened to the landside E, projecting from the standard,and with the other end to the share, as shown.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. The T- shaped bolt D, when arranged to clamp the notched plow orshovel share C to the perforated standard having the projecting rib a.,all made and operating substantially as herein shown and described.

2. The brace E, when arranged in combination with the notched share C,T-shaped bolt D, and standard A, having the rib a, all combined andoperating substantially as herein shown and described.
